Huskvarna Riding Lawn mower will not start

I was mowing the lawn and engine stalled. I determined it was getting fire to the spark plugs. I traced the fuel through the filter to the pump and then replaced the pump without checking the old one. I then removed the fuel line from the carb and cranked the engine - no fuel came out the line. The engine was very low on oil so I filled that thinking the oil pressure switch may have stopped the engine. Any ideas on what I can do to get this running.

Stating the obvious when the fuel line is off the carb and the engine is cranked there should be fuel coming from the hose, if not the pump is not working, there is normally three conections on the pump, fuel in, fuel out, and pulse from the engine, this hose takes a pulse from the rise and fall of the piston in the cylinder, make sure the hoses are connected corectly and tight, if there is still no fuel check the inline fuel filter ( if fitted ) is not blocked, if all appears ok, then it can only be a faulty pump.

does it turn over slow or fast if it turns slowly thats the problem so it could be battery or starter they have to have a good amount of rpms to burn fuel right when starting if not it floods out the engine with gas hope this helps thanks wade

SOURCE: My riding lawn mower won't start. New battery

Spray starting fluid into the air box if it starts and dies out there is a fuel delivery problem if the mower has a petcock fuel shut of valve disconnect the fuel line after the petcock and hold a container under the hose turn on the valve to ensure gas flow to carb if there is no petcock valve I would still check the line to carb make sure gas flows through the hose to carb.

The things you have checked and replaced are not relevant to fault have you described. Only two things are left, Battery and Starter, most probablly your battery is not charged ot it is old enough to hold the charge. If your battery is ok then only and only your Starter is bad , but I think your Battery is bad or not charged. get it charged and then try, if it does not then replace or get the Starter serviced

SOURCE: 10 year old Craftsman Lawn Tractor won't start

I had a similar problem and found that the float was hanging up on the wall of the carb fuel chamber. I sanded lightly the outer edge of the float and never had the problem again. That was 3 years ago. Having a different problem now. After setting overnight in cold weather, 20's, engine turns over very slowly even with a new battery. Engine starts, but barely. Once running, everything seems fine. After shutoff, engine restarts quickly. Next morning, same thing happens. Anyone have any thoughts?

Engine spins but no fire to spark plugs

What is this engine mounted on? If it's on a riding mower, you could have a problem in the interlock wiring that is "killing" the ignition. You can narrow down your search by disconnecting the ground wire that hooks to the ignition coil(s) and see if you have spark after that. If you have spark, then plug the wire back up and see if you lose it again. If you do lose it then you need to start troubleshooting the interlock circuit on the equipment. If you do not have fire with the ignition ground wire disconnected you then need to start looking at the engine ignition system. Hope this gets you in the right direction.

Engins starts and runs when mowing will backfire and stall.

I am not sure what time of lawn mower this is, but if the blade is directly tied to the motor, usually the belt will just slip if not, but if this is directly connected to motor, it might have jumped timing. If this is not the case, inspect under the mower deck, and determine if there is something jamming the blades against the deck or if their is something bound around the blade, this can cause more strain on the motor, which could result in the symptoms your experiencing.

Poulan 6.75 Lawn mower will not start

Remove spark plug, clean and dry. Replace plug. Remove air filter. Spray WD-40 into carb opening; one second blast. Turn over engine, (pull handle). Engine should start briefly and run for 3 seconds.  If not, you are not getting spark to spark plug. If engine starts, you have a dirty carb and you can buy a rebuild kit from manufacture.
